Installer and updatesite-core zip contain different timestamps for JBDS product IU ---------------------------------------------------------------------------------- Key: JBDS-3532 URL: https://issues.jboss.org/browse/JBDS-3532 Project: Developer Studio (JBoss Developer Studio) Issue Type: Bug Components: updatesite Affects Versions: 9.0.0.CR2 Environment: jboss-devstudio-9.0.0.GA-v20150925-1252-B116-installer-standalone.jar jboss-devstudio-9.0.0.GA-v20150925-1252-B116-updatesite-core.zip downloaded from http://www.qa.jboss.com/binaries/RHDS/9.0/staging/builds/devstudio-9.0.0.... Reporter: Jan Richter Priority: Blocker The updatesite zip has a later timestamp than what you get from the installer but it is still the same build. So you can basically update to the same build because of that.
